IM PROVEM ENT IN GATES.

Specification forming part of Letters Patent No. 199,341, dated January15, 1878; application filed October 17, 1877. I

To all whom it may concern Be it known that I, ROBERT YALE, of Afton, inthe county of Ohenango, and in the State of New York, have inventedcertain new and useful Improvements in Gates; and do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing bad to the accompanying drawings, making a part of thisspecification, in which-- 'Figure l is an elevation of the side of myimproved gate, and Fig. 2 is a like view of the same when swung open.

Letters of like name and kind' refer to like parts in each of thefigures.

The design of my invention is to suspend a gate upon a post in such amanner as to enable it to be easily and freely swung open, all saggingof its outer end prevented, and said gate caused to automatically close;to which end it consists in the means employed for suspending the gateto or upon its pivotal post, substantially as and for the purposehereinafter specified.

In the annexed drawing, A represents the top rail, B and B the lowerhorizontal rails, and G the vertical bars, of a gate of ordinary formand construction. The top rail A extends rearward about onethird thelength of the gate, and, at a point just in rear of the rear ends of therails B, rests upon the upper end of a post, D, where it is held inplace horizontally, by means of a pivotal stud, d, that is securedwithin and projects upward from said post, and fits into a correspondingopening in said rail.

The rear end of the rail A is cut away upon a rearward and downwardinclining line, and through such portion passes the upper threaded endof a rod, E, which rod, at its lower end, is pivoted to or upon aneyebolt, F, that is secured within and projects horizontally rearwardfrom near the lower end of the post D.

A nut, e, placed upon the upper threaded end of the rod E, bearingagainst the inclined face of the rear end of the rail A, insures therelative positions of said parts, and enables such portion of said railto be depressed or elevated, so as to cause the outer end of the gate tobe correspondingly raised or lowered.

As thus arranged, it will be seen that the weight of the front end ofthe gate is sustained by the rod E, while, as the lower end of said rodis pivoted to or upon the post I), nearly in a line horizontally withthe pivotal bearing (1, said gate is permitted to swing open with nearlyor quite the same freedom as though ordinary hinges were employed aspivotal bearings.

In consequence of the slight variation in horizontal position of thepivotal bearing-pin d and the eyebolt F, the rod E causes the rear endof the rail A to be depressed and the outer end of the gate to be raisedas said gate is opened, the amount of such elevation being sufficient tocause the latter to close automatically when released.

Whenever the weight of the gate or the action of water or frost hascaused the post D to change its position, said gate may be leveled upagain by turning the nut e upon the rod E, as before explained.

Having thus fully set forth the nature and merits of my invention, whatI claim as new As a means for suspending the gate to or from the post D,the rearward extended top rail A, resting upon said post, and pivotedthereto by the stud d, the rod E, having its threaded upper end passedthrough the rear end of said rail, and secured in place by the nut e,and the eyebolt F, secured within the lower end and rear side of saidpost, and having pivoted thereon the lower end of said rod, said partsbeing combined to operate in the manner and forthe purpose substantiallyas specified.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 15th day of September, 1877.
